Still haven't gotten this off yet. Every friggin bolt is rusted on and the heads shear off while trying to remove them. What would probably be a weekend project is taking all friggin year! Anyone else have a problem with the bolts on these old dozers?

If you are talking about the center bolt that goes in the axle it should break free before turning the axle. It clamps the cap to the axle. I'm wondering why you have not put a wrench on it yet? Can you post a photo of the offending bolt? JT I wont be out to my property where the dozer is for a cou...

The reason I ask is that the head of the outside retaining bolt is sheared off by the looks of it. When undoing the opposite bolt on the inside will the axle just spin because there is no bolt securing it on the other side, not allowing the inside bolt to extract. I wonder if I can use a bolt extrac...

Is the axel loose in the idler wheel or is it pressed in?

No one out there has had to replace or remove the idler?

This is on the starboard side of the crawler, It appears that the outside bolt head that anchors the idler in place sheared off allowing the idler to eat through the cast iron bracket around it. I'm guessing that the bolt head sheered off because when you look into the axel of the idler there is sol...

Found this this weekend while doing routine inspection of the dozer. The cap screw must of backed out and was lost at somepoint before I ran it last time cutting about a 1/2 mile trail through the woods. The whole assembly looks trrashed. Definetly the outside idler bracket. Any thoughts on what els...

I was hoping it was in the tech manual, but it wasn't. I may have broken loose a wire when I was replacing the fuel filters and that may be it, but I'm not sure where it connected.

Does anyone know where the positive wire for the hour meter connects on the dozer? Mine stopped working and I want to find its terminus.
Thank you.

Thank you. That is what I thought.

The manual calls for two different oils, one for winter and one for summer use with the dividing line temperature being 32 degrees F. In the winter in WV we can have days on both sides of that line. I'm guessing they didn't have the multi-viscosity oil available in the mid-70's that they have now an...

Thanks for the replies and the tips!

A couple of questions for those of you who have conducted major fluid changes in the past. I don't want to have to reinvent the wheel when I have your experience to draw from. I plan on changing the transmission fluid (9 gallons) and the hydraulic fluid (13 gallons). First, what are you guys drainin...

Check the filter in the bottom of the tank also. It would be more likely to cause the hydraulic system to stop working. Clean the bottom one and replace that reservour filter.
